MG S6 vs Nissan Ariya

The MG is the value winner, and it is not close. As of September 2026 the S6 Essence RWD is $49,990 driveaway, the same price as the Ariya Engage, yet it claims 145km more range, carries a bigger boot plus a frunk, and fits heated and ventilated seats, a head-up display, a 360 camera and dual-zone climate as standard where the Engage does without them. To match that kit in an Ariya you step to the $61,990 Advance+, about $12,000 dearer. The Ariya's answer is refinement and brand reassurance rather than value. Both prices move with offers, so confirm the current driveaway figure, but on equipment and space for the money the S6 wins decisively.

The MG leads on range. Its Essence RWD claims 530km on the WLTP cycle to the Ariya Engage's 385, and even the S6 AWD manages 485km, close to the Ariya's flagship. The longest-range Ariya, the 87kWh Advance+, claims 504km, still short of the base MG. On charging they are close: the S6 peaks at 144kW DC to the Ariya's 130, and quotes 38 minutes from 10 to 80 per cent on its bigger 77kWh battery, while the Ariya quotes about 35 on its smaller 63kWh pack, so a highway stop takes a similar half-hour in each. Both are lab figures and both charge fully overnight at home. On range the MG is the clear winner; on charging it is a draw.

The S6 is the roomier car throughout. Seats up its 581-litre boot beats the Ariya's 466, and it adds an 86-litre front boot for charging cables where the Nissan has none. Fold the rear seats and the MG opens to 1690 litres to the Ariya's 1350. Reviewers rate the S6's rear-seat space among the most generous in the segment, helped by a flat floor and an ultra-thin battery pack. The Ariya is far from cramped, and both are five-seat SUVs of similar length, but on boot volume, front storage and back-seat room the MG has the clear advantage, which makes it the stronger pick for families who carry a lot.

Both carry a five-star rating, the S6 off 2025 testing and the Ariya from 2022, so neither is a compromise. They earn it differently. The MG is the stronger crash performer, scoring 92 per cent for adult-occupant protection to the Ariya's 86, and it leads on vulnerable-road-user protection, 84 to 74. The Ariya answers on safety assist, a strong 95 per cent to the S6's 81, and edges child occupants, 89 to 87. Each fits seven airbags, the S6 including a front-centre bag, and the full driver-assistance suite as standard. The MG has the newer test and the crash-protection edge; the Nissan the stronger assist score. On the record it is a genuine wash.

Both are rated to tow 1500kg braked and 750kg unbraked, but they reach it very differently. The MG S6 tows 1500kg on either grade, from $49,990 driveaway as of September 2026. The Ariya's front-drive grades manage only 750kg, and it takes the $75,990 Evolve e-4ORCE to match the MG's 1500kg. So if towing a small camper or a box trailer is on your list, the S6 does it for less than half the price of the tow-capable Ariya. Neither is a heavy hauler by ute standards, but for occasional light towing the MG is comfortably the cheaper way to get the capability, and it is standard across its range.

Both are tuned for comfort rather than sharpness, and reviewers rate each as a quiet, relaxed EV to live with. The difference is ride polish. Several testers find the S6 firm and a touch busy on its standard 20-inch wheels over patchy urban roads, with a little more vertical movement than the smoothest rivals, though its refinement and cabin quietness draw praise. The Ariya is the more settled of the two, its ride among the reasons AU reviewers rate its cabin the calmest in the class. Neither is a driver's car, and the S6 AWD is far quicker in a straight line. But for outright ride comfort, the Nissan has the edge, while the MG counters with pace and space.

This one leans the MG's way. The S6 carries a seven-year, unlimited-kilometre warranty, extendable to 10 years or 250,000km if you service within MG's network, to the Ariya's five-year, unlimited-kilometre cover. It also services less often, every 25,000km to the Ariya's 15,000, cutting workshop trips. Both offer up to 10 years of roadside assistance when serviced with the brand, and both back their batteries for around seven to eight years. As the more efficient car the S6 uses less energy too, 145Wh/km to the Ariya's 184. On balance the MG is the stronger ownership case on paper, led by the longer standard warranty and less frequent servicing, with the Ariya's brand track record the counterweight.

Both punch above expectations, for different reasons. The S6's cabin surprises reviewers for its money, with vegan leather and suede, soft-touch materials and retained physical climate controls, and it fits a 12.8-inch touchscreen, a head-up display, a 360 camera and dual-zone climate as standard on both grades. The Ariya answers with atmosphere, a hushed, airy space rated the class's most restful, a larger 12.3-inch driver's display and over-the-air software updates the MG goes without. The MG's software has no remote updates and drew the odd glitch in reviews. So the S6 is the more loaded, premium-feeling cabin for the money, the Ariya the calmer and more up-to-date one.

It comes down to spec against polish. If you want the most space, range and equipment for the money, the S6 is the pick: at the Ariya Engage's $49,990 as of September 2026 it gives you 145km more range, a bigger boot and frunk, more standard kit and 1500kg of towing, in a cabin that feels a class above its price, provided you can accept a firmer ride on its 20-inch wheels, no over-the-air updates and MG's still-forming resale story. If you value a more settled ride, the calmest cabin in the class, a stronger driver-assist suite and the reassurance of a proven brand, the Ariya earns its premium, though you reach comparable kit only at the $61,990 Advance+. Weigh spec-sheet value against refinement and brand, and the answer follows.
